I love theoretical physics
I love proving general theorems about an unfathomable number of possible physical systems in parallel
Major part of my meaning of life currently is to try to understand:
- The most complete fundamental equation/s of intelligence: human intelligence, diverse machine intelligences (all sorts of current and future subfields of AI), other biological intelligences, collective intelligence, theoretical perfect AGI (AIXI variants, Chollet's intelligence, Legg's intelligence, etc.), hybrids, etc.
- The most complete fundamental equation/s of the universe and the world in general: How does the standard model and general relativity work? How does everything else in our world on other scales with other fields, such as chemistry, biology and sociology, emerge? What is beyond the standard model of particle physics and general relativity, how to solve quantum gravity?
Standard model should be called special relativistic quantum field theory instead of just quantum field theory to minimize confusion, because you can have quantum fields without special relativity
Did you know that the expansion of the universe breaks energy conservation on cosmic scales?
[Reddit: If the universe is constantly expanding, how is the law of conservation of energy obeyed?](<https://www.reddit.com/r/askscience/comments/11w9asm/if_the_universe_is_constantly_expanding_how_is/>)
https://bigthink.com/starts-with-a-bang/expanding-universe-conserve-energy/
maybe out heories are wrong, or maybe this is just the feature of our universe
to by asi vesmír musel neexpandovat 😄 expansion breaking time-translation symmetry corresponding to breaking conservation of energy seems to be pretty solid 😄
hmm, koukám že existuje nějaká [Tired light teorie](<https://thedebrief.org/time-to-rethink-the-big-bang-new-research-suggests-universal-expansion-may-not-be-what-it-seems/>) nebo [Energy conservation drives the expansion of the universe](<https://arxiv.org/abs/2212.01269>)
Složitost/komplexitu může entropie někdy jen aproximovat
Maximální entropie je thermodynamic equilibrium (death of structure), a minimální entropie je perfect crystalline solid v absolutní nule, a obojí má celkem malou complexity tak jak complexity chápeme
I když vlastně, ten vztah mezi těmato veličinama by šel možná popsat takhle v The First Law of Complexodynamics

I want to make every fundamental particle of the universe into an original character and create a cartoon series where they interact with each other.
A photon character would endlessly shine light with wholesome energy, a gluon character would connect others together with the magic of friendship, an electron character would electrically power and energize everything possible, a higgs character would help others with identity, up and down quark characters would together through cooperation form structures in the world, strange quark and neutrino characters would be mysterious and ghostly, and then there would be a charm character, or top and bottom quark characters, and the colors of the quark characters could correspond to their color charge.
You could explain how photons are visible light, radiation, x-ray. From big bang to now symmetry breaking. Vacuum decay. Zip zapping electrons. What makes all particles special. How's were particles measured in cern. Gravitons. Generál relativity. Tachyons. Loop quantum gravity. String theory. Causal sets. Quantum field theory. How was special relativistic quantum field theory discovered starting with aristotelian mechanics, classical mechanics, quantum mechanics. Higgs boson.

je to mega cool
a je to generalizace klasickýho principle of least action co je v klasický mechanice, a relativita to má taky
afaik alternativa feynmanovy path integral formulace kvantový mechaniky je např Shrondingers picture (klasická Schrondingerova rovnice) a Heisenberg's picture a Dirac picture https://en.wikipedia.org/wiki/Schrödinger_picture https://en.wikipedia.org/wiki/Heisenberg_picture https://en.wikipedia.org/wiki/Interaction_picture
je jich víc

jsou ekvivalentní ve smyslu že dají úplně stejnou evoluci initial stavu kvantovýho systému, mají identický information content

I mean I love exploring the space of all possible formulas and mathematical structures in applied/pure mathematics, or more generally all possible informal and formal thoughts in philosophy.
But when it comes to physics, I think the issue is that you can come up with infinite amount of possible mathematical formulas, since the space of all of them is so large, then when it's not grounded in how it connects to existing or potential other physical experiments, to actually verify if the math is empirically predictive, then it feels like it's very arbitrary.
maybe quantum wave function is not fundamental but emergent from something more fundamental according to superdeterminism interpretation of quantum mechanics https://arxiv.org/abs/2109.02676

Which theories of everything are the closest to truth? String Theory (vibrating strings, extra dimensions), Loop Quantum Gravity (quantized spacetime, spin networks), Causal Set Theory (discrete events, fundamental causality), Digital Physics (universe as computation, information fundamental), Asymptotically Safe Gravity (quantum gravity, high-energy fixed point), Twistor Theory (twistors fundamental, spacetime derived), Causal Dynamical Triangulation (spacetime from simplices, causality), E8 Theory (E8 Lie group, controversial unification), Gauge Theory Approaches to Quantum Gravity (gravity as gauge field, recent), Noncommutative Geometry (non-commuting coordinates, abstract unification)?
Do you have some favourite attempt at a theory of everything in physics?
I like Causal sets on vibe level. But I still need to dig into its math.
"The causal sets program is an approach to quantum gravity. Its founding principles are that spacetime is fundamentally discrete (a collection of discrete spacetime points, called the elements of the causal set) and that spacetime events are related by a partial order. This partial order has the physical meaning of the causality relations between spacetime events."
It's very Wolframian as well, but more accepted by academia.

Everything is stochastic differential equations

What approximates you the best and when???! How to merge these perspectives in various regimes on you?!?!!! GAAAAAAAAAH stop CONFUSING US tell us YOUR NATURE!!!!
In general relativity, time should be called generalized time and proper time should be called time.
B stands for bagnetic field
Biology is to first approximation a subset of dissipative self-replicating physical systems that are far from thermodynamic equilibrium by continuously eating free energy and spitting out entropy

There's superderminism
Wiki https://en.wikipedia.org/wiki/Superdeterminism defines it as:
"In quantum mechanics, superdeterminism is a loophole in Bell's theorem. By postulating that all systems being measured are correlated with the choices of which measurements to make on them, the assumptions of the theorem are no longer fulfilled. A hidden variables theory which is superdeterministic can thus fulfill Bell's notion of local causality and still violate the inequalities derived from Bell's theorem.[1] This makes it possible to construct a local hidden-variable theory that reproduces the predictions of quantum mechanics, for which a few toy models have been proposed.[2][3][4] In addition to being deterministic, superdeterministic models also postulate correlations between the state that is measured and the measurement setting."
On testing:
"It is possible to test restricted versions of superdeterminism that posit that the correlations between the hidden variables and the choice of measurement have been established in the recent past." (source <https://pmc.ncbi.nlm.nih.gov/articles/PMC2993398/>)
"In general, though, superdeterminism is fundamentally untestable, as the correlations can be postulated to exist since the Big Bang, making the loophole impossible to eliminate." (source <https://www.theatlantic.com/science/archive/2017/02/spooky-action-at-a-distance/516201/>
"According to the physicist Anton Zeilinger, if superdeterminism is true, some of its implications would bring into question the value of science itself by destroying falsifiability:
[W]e always implicitly assume the freedom of the experimentalist... This fundamental assumption is essential to doing science. If this were not true, then, I suggest, it would make no sense at all to ask nature questions in an experiment, since then nature could determine what our questions are, and that could guide our questions such that we arrive at a false picture of nature."
And Sabine has a paper on Testing super-deterministic hidden variables theories "We propose to experimentally test non-deterministic time evolution in quantum mechanics by consecutive measurements of non-commuting observables on the same prepared state. While in the standard theory the measurement outcomes are uncorrelated, in a super-deterministic hidden variables theory the measurements would be correlated. We estimate that for macroscopic experiments the correlation time is too short to have been noticed yet, but that it may be possible with a suitably designed microscopic experiment to reach a parameter range where one would expect a super-deterministic modification of quantum mechanics to become relevant." <https://arxiv.org/abs/1105.4326>
Which is being criticized:
"Hossenfelder’s proposed experiment has a critical and fairly obvious flaw: it cannot falsify superdeterminism. Therefore, it’s not a valid experiment, for we’ve known since Popper in the 1960s that valid experiments motivated by a hypothesis are supposed to be able to falsify the hypothesis. More specifically, if Hossenfelder’s experiment shows little time-correlation between the distinct series of measurements, she can always (a) say that the series were not carried out in sufficiently rapid succession, so the initial state drifted; or (b) say that there aren’t enough samples in each measurement series to find the correlations. The problem is that (a) and (b) are mutually contradictory: a long series implies that the next series will happen later, while series in rapid succession imply fewer samples per series. So the experiment is, by construction, incapable of falsifying hidden variables. In conclusion, no, hidden variables have no empirical substantiation, neither in practice nor in principle; neither directly nor indirectly."

Teď se snažím jít primárně směrem pochopení matiky za standardním modelem částicový fyziky
Someone:
Přemýšlel jsem o nepředvídatelnosti.
V realitě budoucnost je deterministická, ale minulost je nevypočitatelná. Ve filmech je to ale často naopak.
Me:
Hm, co kvantovka?
Nebo dost nekvantových procesů se musí modelovat pravděpodobnostně, aby to bylo tractable
Co se týče deterministický budoucnosti
Nebo můžeš předpokládat superdeterministickou interpretaci kvantový mechaniky, a potom by měla jít v teorii (ale spíš ne v praxi) vypočítat i minulost i budoucnost. Ale většina interpretací kvantovky má v sobě pravděpodobnosti, kde kolaps vlnový funkce určující pravděpodobnosti rozbíjí reversibility.
Plus v praxi i irreversibility thermodynamiky to rozbíjí
A teorie chasu ještě dělá v praxi bordel v tomhle
Plus ta computationally infeasible komplexita reality in practice
Someone:
Mě by zajímalo jaký by to mělo implikace pro matematiku (a obecně) kdyby minulost byla deterministická.
Jaká by byla pointa paměti, kdyby se dala vždy minulost dopočítat ?
Me:
Caching
Ale realita je moc komplexní atd. na to aby šla minulost dopočítat
I když předpokládáš superdeterministickou interpretaci kvantový mechaniky
Plus není to jen o determinismu, je to i o reversibility, a spousta emergentních fyzikálních zákonů nejsou reversible a používají se tam pravděpodobnosti
Počítat všechno ze Standardního modelu částicový fyziky emergentně je taky v praxi intractable
ve fundamentální fyzice ses limitovanej proveditelnosti experimentu
>musí postavit ten větší urychlovač no
dost fyziků by s tebou nesouhlasila
a argumentují že ty prachy co dát do většího urychlovače by se víc vyplatilo dát do menších levnějších experimentů
nedávno jsem viděl např nějaký nový results k loop quantum gravity
ale zatím o tom vím tak málo že sám netuším lol, ale dle fyziků ty data o loop quantum gravity šly spíš směrem falzifikace než potvrzení
